Is changing artificial gravity structure possible?

Maybe... in Space

You need constant _acceleration_ to simulate gravity, not just any old motion, which is why that's not a popular method even in soft sci-fi (the only examples I can think of are some long burn torchships that accelerate halfway there, turn around, and decelerate the other half of the way). Anyway, you might find something useful on Atomic Rockets https://projectrho.com/public_html/rocket/artificialgrav.php

Fair enough

If I'm understanding your diagrams correctly, this is how the pods on the Argo in Battletech work.

Had to do some research and yes absolutely!
Though those pods seem to use the concept in a more efficient way.
Mine has a single continuous habitat that doesn’t use modules. Likely complicating it to a ludicrous degree and might not be possible

Yeah, the continuous ring seems difficult to change orientation. Maybe if it was connected by many struts, each hinged at different points, so different segments of the ring could be reoriented at different alignments along the ship, without needing to alter the circumference. Still a lot of engineering considerations but you might be able to come up with improvements on the idea. Or an even better idea.

It's indeed a possibility, but you need a lot of Phlebotinum.

Not really. If you don't have homemade, store-bought unobtanium is fine.

Maybe. But have you seen the PRICE of that stuff?

Yea but that is why we will borrow a mater-replicator

remember to slow down rotation as you increase directional drive or your riders are going to have a bad time

Not to mention the wear on the inside edge of your tires.

OP, have you ever flown on an airplane before? 500+ miles/hour, and yet you aren't constantly pinned against the back of your seat or reduced to paste from the force, right? You can feel it when the plane is taking off, but that stops once the plane stops accelerating. To achieve artificial gravity this way, you would need to accelerate constantly, which is problematic for a number of reasons- fuel/energy, collision danger, reaching your destination instead of sailing clean past it, etc.

Yes, i am aware of the set backs of using thrust gravity.

That is actually the point of this possible schizo-diagram (schizogram if you will)

The ability to switch between two forms of artificial gravity allows a permanent green and water habitat while:
1. Be able to accelerate without turning off the gravity
2. Be able to have gravity when it isn’t moving or coasting

Just do spin 'gravity' on the ring. Then forward acceleration while applied slowly, wont have a hugely negative effect. I assume what ever this is for, there does not exist FTL or such, else you would just have used grav plating or some such.

Oh, I see, I understand your diagram now, forgive me. Would the transition between states be a problem, though? During the transition, artificial gravity would be applying unevenly (in a non-orthogonal direction) to the living surface.

It’s no problem, I lack a lot of the expertise to even convey my questions easily.
To answer your question: probably.
I would imagine that as it begins moving linearly that it begins to decelerate the spin (through some convoluted mechanics or calculations) and angles the habitat. So it basically becomes half of both as it transforms. However I don’t know enough of the physics to know if the combination of the two as it transitions is disruptive.
